Two-stage Prosthetic Prepectoral Breast Reconstruction: Comparing Tissue Expansion with Carbon Dioxide and Saline.

BACKGROUND: The AeroForm tissue expander is a carbon dioxide-filled breast tissue expander that allows gradual, needle-free expansion using a hand-held remote controller. This study evaluates 2-stage, prepectoral tissue expander-to-implant breast reconstruction with the carbon-dioxide tissue expanders and compares the outcomes to our recent experience with saline tissue expanders. METHODS: This was a retrospective study of consecutive patients from a single institution. The subjects consisted of women who underwent mastectomy and either immediate or delayed breast reconstruction with AeroForm or saline tissue expanders. Outcomes encompassed postoperative complications including mastectomy flap necrosis, infection requiring readmission and/or intravenous antibiotics, capsular contracture, hematoma, seroma, skin dehiscence, extrusion, premature explant, and loss of communication with the device (AeroForm) or rupture of the device (saline). RESULTS: This study evaluated 115 patients with 185 breast reconstructions. Of the 185 breast reconstructions, 74 (40%) utilized AeroForm tissue expanders and 111 (60%) utilized traditional saline tissue expanders. Treatment was successful in 100% and 94% in the AeroForm and saline groups, respectively (P = 0.025). The incidence of adverse events was greater in the saline group (45.9% versus 32.4%). Surgical-site infection occurred more commonly in the saline group (5.4% versus 0%). Full-thickness skin necrosis occurred at a significantly higher rate in the saline cohort as compared with AeroForm (5.4% versus 0%). CONCLUSIONS: The use of AeroForm tissue expanders offers notable advantages for breast reconstruction. This device when employed in the prepectoral space may be associated with reduced infection rates and decreased utilization of healthcare and patient resources.

An effective technique for salvage of cardiac-related devices.

Millions of patients require implantable cardiac devices for management of cardiac dysrhythmias. These devices are susceptible to erosion, exposure, or infection and plastic surgeons are consulted when salvage is required. As of yet, an anterior muscle-splitting approach to effectively and safely relocate the device into the subpectoral position has not been described in the plastic surgery literature. The authors retrospectively reviewed the charts of 7 patients who required repositioning of cardiac devices. Indications for repositioning included exposure, erosion, infection, hematoma at the time of primary placement (3), and one cosmetic revision. All patients were treated with subpectoral repositioning of the device into the subpectoral space via an anterior muscle-splitting approach. Six of 7 patients (86%) achieved successful long-term repositioning in the subpectoral position without recurrent exposure or hematoma and with good cosmetic results. One patient who had a prior history of multiple failed device placements required reoperation due to recurrent infection. The anterior muscle-splitting technique proposed by the authors for defibrillator or pacemaker salvage is a feasible technique with promising results. Plastic surgeons should be aware of this simple and effective approach.
